Description
Overview:
This Elbow Connector is a Genuine Stihl OEM part designed for the 1123-series chassis used on popular chainsaws such as the MS 250 and MS 250 C. It forms a right‐angle junction between small-bore hoses or tubes inside the saw, maintaining a secure, sealed path for fuel, oil, or air as required by the system layout. Made from tough, black OEM-grade material engineered to resist vibration, heat, and exposure to petrol and chain oil, it helps prevent leaks and air ingress that can affect starting, idling, and overall performance. Built to Stihl's specifications for fit and durability, it is a direct replacement under MPN 1123 122 3900, supporting reliable operation and straightforward maintenance for both professional and DIY users.
Key Features:
- Genuine Stihl part for assured compatibility and long service life (MPN: 1123 122 3900)
- Precise 90-degree form to route hoses cleanly in tight spaces without kinking
- Durable OEM-grade material resists petrol, oil, heat, and continuous vibration
- Exact fit for the specified Stihl chassis range to restore factory performance
- Helps prevent fuel and air leaks that can cause hard starting or poor running
- Simple to install during routine servicing with basic hand tools
- Stable sealing surfaces to maintain system integrity over time
- Ideal as a preventative replacement when original elbows become brittle or cracked
Typical Applications:
Replacement of a worn, cracked, or hardened elbow in the chainsaw's fuel, vent, or impulse routing.
